.6 Claims.

This invention is a shoe and process of making.

It has particular reference to the manner of connecting the upper with the inner sole and the outer sole and more particularly to shoes made according to the so-called Compo process.

In the Compo process, the margins of the upper are cemented to the inner sole and also to the outer sole usually by a cement of such a character that it keeps the air from getting under the sole of the foot or into the stocking with the result that there is a tendency to perspire and more or less of a burning sensation.

I am aware that there are shoes with insoles having perforations and also shoes having `Fillers or pads of felt and other similar material and that there are elaboratesystems for Ventilating or circulating air between the insole and the outsole.

A particular purpose of this invention is to provide an elastic cushion under the ball of the' foot and adjoining parts, between part of the insole and part of the outsole, which is so located and attached that as the foot is flexed in walking, the air in certain parts is compressed and then released thereby Ventilating the space under the foot and also assisting in providing a cushion for the foot.

In the drawing, Fig. l isa side elevationv with parts broken away of a shoe of my construction.

Fig. 1A is an enlarged sectional view of a detail.

Fig. 2 is a View of an inner sole of my construction as it would appear from the upper side or the side which is inside the shoe.

Fig. 3 is a view of the same inner sole showny in Fig. 2 from the opposite side.

Fig. 4 is a sectional view much enlarged, of part of the sole shown in Fig. 3 looking in the direction of the arrow on the line 4-4.

Fig. 5 is a detail sectional View similar to Fig. 4, showing the upper, patch, inner sole and tape as they appear during the next step in the proc-- ess of assembling.

Fig. 6 is a View similar to Fig. 5 showing the complete connections between the outer and inner soles, the upper, the patch, the tape and the pad.

Fig. 7 is a view similar to Fig. 2 of a modification and Fig. 8 is a view similar to Fig. 6 of the modification shown in Fig. 7.

Fig. 9 is a view similar to Fig. 8 and Fig. 6 of another modication.

In the drawing U represents an upper assembly of any usual type with the side margin 4 and the iront margin 6. These are the partsin the formation of the shoe,- Where the upper isy pulled or bedlasted over the last in the manufacturing process and which are attached to the insole and to the outer sole.

H is any ordinary heel, I is` the insole, O is the outsole and P is a patchwhich, as shown in Figs. 1 to 6, is perforated to form a plurality of holes I0; IU, rows of which are within a short distance of its margin Il.

Inner sole I has acut out 3 into which a cushion R nts but projects a substantial distance. As shown in Figs. 3 to 6, running down along each side of cut out 3, there are two tapes or strips such at T, T.

These are in such a position that two rows of stitchingy S, S, can go through the margins H,

l I, of patch P, and border 8 of inner sole I near cut out 3 and also through a tape T near its outer part I. The other part 2 can be. lifted or ploughed up in a later process so as to attach it by staples A, A, to the margin 4 of the upper U as shown in Fig. 5. These staples A, A, go

through the margin 4 of the upper U andthe part 2 of a tape T.

As shown in Fig. 5, part of each margin 4 and oi' a tape T are then cut partly off as shown by the dotted line X-X in Fig. 5 after which, what is left 5 of the part 2 of tape T is flattened down so that there is left a channel 9 over which the outer sole O is fastened, this channel therefore being iilled with air as shown in Fig. 6.

The fit of the cushion R in the cutout 3 is not close and its resiliency makes the connection between this air channel 9 and the adjoining rowA of holes l0, I0, such that the air can circulatev r through and between them as the forepart of the shoe is flexed, the cushion R being resilient and the action causing the air to so circulate.

In attaching the upper and the soles together to make the iinished shoe, the upper is iirst assembled and the inner sole with its cut out part 3 has attached to it by stitching S the tapes T, T, and the patch P.

-This inner sole is now attached to a last L in any usual manner as by several tacks. The cushion R can be placed in the cut out 3 and may be held in place as by cement 33 a't the front and back. The upper is now placed over the last or the upper can be first put on the last and thenv the inner sole canl be tacked in place.

The margins of the upper are now pulled over and the front part 6 andthe back part are fastened in place by a number of tacks in the usual way. Cement 34 is now spread or sprayed between the margin 4 of the upper, the border 8 of the innersole and the part I of tape T. The edge of margin 4 of the upper U and part 2 of a tape T are now, on an appropriate machine, or by hand, lifted up together to the position shown in Fig. 5 and staples A, A, are forced through them thus holding them together While the toe is bedlasted.

Along the lines X, X, of Fig. 5 the rim of margin 4 of the upper U and the rim of part 2` of a tape T are now cut off together with the staples. The rest 1 of margin 4 and the rest 5 of part 2 are now pressed down and roughed with a wire brush so that, as shown in Fig. 6, the cement at will hold the outer sole O to these parts leaving the space 9 between the cushion R and the outer sole uncemented whereby air can circulate between them through the channels such as 9 and, as stated, through the holes lll, I0, in the patch P and also into and out from the space B, shown in Figs. 1 and 3 beyond the end of cushion or pad R between the edges of the rest 1 of margin 4 and of the rest 5 of part 2, towards the heel.

As shown in Figs. 'l and 8, the tapes such as T and the stitching S can be omitted, the inner sole 40 having a cut out 4|A and a patch 42 with holes 43 attached by cement 44 there being also a cushion 45 which projects outward from inner sole 40 the same distance as the thickness of the margin 46 of the upper 4l, there being a space 49 `between the edge of margin 46 and the edge oi cushion 45, the upper being attached to the inner sole 40 by cement 48.

50 is an outer sole attached in any usual way, as by cement 36, thus closing the space 49 and making it an air channel. It will be noted that the cut out part 4l is round and the patch 42 as shown is made of muslin or other'open meshed cloth. The holes 43, 43, are those naturally formed between the Warp 5I and filling 52. It will also be noted that the cushion 45 is shown as made of cork while the cushion R is shown as made of rubber. This cushion may be of either cork, sponge rubber or a combination of rubber and cork or in fact, of any other resilient material which is preferably penetrable by air.

It will also be noted that the cushion is preferably attached by adhesive to the patch at the front andY back only and the patch is attached to the inner sole at the front and back only as this construction allows more movement of the air as the foot is exed thus aiding the circulation.

I believe I am also the first to use tapes inthe manner indicated and in Fig. 9, I show a modification of the construction in which 53 is the upper and 54 the inner sole, which has no cut out but has one or more holes 55. 56 is a tape fastened to the inner sole 54 as by the stitching 51, and 58 is a pad interposed between inner sole 54 and the outer sole 59.

The tape 56 and the margin 60 of the upper 53 have been treated in the same manner as shown in Figs. 4, 5, and 6. The margin 60 of upper 53 has been stapled to tape 55 and then their rims and the staples have been cut off leaving them as shown in Fig. 9, margin having then been stuck to the tape 56 and to the inner sole 54 as by adhesive 6| while the outer sole 59 has been stuck to the margin E0 of the upper as by an adhesive 62.

I claim:

1. The process of making a shoe which consists in providing an inner sole having a cut out in the forepart and stitching tapes extending lengthwise from near the heel to near the toe on both sides of the cut out, the same stitching attaching a perforated patch on the' other side of the nsole; positioning a resilient pad in the cut out so that it projects between the tapes; temporarily attaching the inner sole with the tapes, patch and pad to a last; placingan upper on the last; smearing adhesive between the outside edge of the tape and the outside edges of the border of the inner sole; lifting up the inner rim of each tape and pulling over the margin of the upper and stapling the uplifted rim of a tape and lthe rim of the margin of the upper together; allowing the adhesive to set; then cutting off part of the rim of the upper and part of the inner rim of the tape inside the staples; and then attaching an outer sole by an adhesive to the remaining parts of the margin of the upper and of the tapes.

2. The combination in a shoe; of an inner sole having a cut out in its iorepart and a tape stitched on each side from proximate the heel to proximate the toe; a perforated patch which extends over the cut out part and is fastened in place on each side by the stitching which also attaches a tape; a resilient pad attached at front and back to the patch, positioned in and projecting out from the cut out part of the inner sole; an upper the margin of which extends over the outer border of the inner sole and over` part of a tape, the margin of the upper being fastened to the border of the inner sole by an adhesive; and an outer sole fastened to the margin of the upper by an adhesive and extending over the pad in such a manner that there are air channels Vbetween the pad, the tape and the edge of the margin of the upper.

3. The combination in a shoe; of an inner sole having a tape stitched on each side from proximate the heel to proximate the toe and having one or more perforations; a resilient air penetrable pad projecting out from the inner sole; an upper, the margin of which extends over the border of the inner sole and over part of a tape, the margin being fastened to the border of the inner sole by an adhesive; and an outer sole fastened to the margin of the upper by an adhesive and extending over the pad in such a manner that there are air channels between the pad, the tape, and the edge of the margin of the upper.

4. The combination in a shoe; of an inner sole having a tape stitched on each side from proximate the heel to proximate the toe the inner sole having one or more perforations; a resilient pad with vertical edges projecting out from the inner sole; an upper, the margin of which extends over the border of the inner sole and over part of a tape so as to leave a channel between it and the projecting edge of the pad, the margin being fastened to the border of the inner sole by an adhesive; and an outer sole fastened to the margin of the upper by an adhesive and extending over the pad in such a manner that there are longitudinal air channels between the pad, each tape, and each edge of the margin of the upper.

5. The combination in a shoe; of an inner sole having a tape attached on each side from proximate the heel to proximate the toe the inner sole having one or more perforations; a resilient pad with vertical edges projecting out from the inner sole and attached only at its front and back, an upper, the margin of which extends .over the border of the inner sole and over part of a tape so as to leave a channel between it and the projecting edge of the pad-the margin being fastened to the border of the inner sole by an adhesive; and an outer sole fastened to the margin of the upper by an adhesive and extending over the pad in such a manner that there are longitudinal air channels between the pad, each tape, and each edge of the margin of the upper.

6. The process of making a shoe which consists in providing an inner sole and attaching tapes extending lengthwise from near the heel to near the toe on both sides; temporarily attaching the inner sole with the tapes to a last; smearing adhesive between the outside edges of the tapes and the outside edges of the border of the inner sole; placing an upper on the last; lifting up the inner rim of each tape and pulling over the margin of the upper and stapling the up lifted rim of the tape and rim of the margin of the upper together; allowing the adhesive to set; then cutting off part of the rim of the upper and part of the inner rim of the tape inside the staples; of positioning a pad proximate to and attaching it only at its front and back to the nner Sole between the tapes so that it projects from the inner sole beyond the tapes; and then attaching an outer sole by an adhesive to the remaining parts of the margin of the upper and of the tapes.
